About Statfarads
The statfarad (statF) is the capacitance unit of the CGS-Gaussian system, equal to exactly 10⁵/c² F where c = 299 792 458 m/s, giving ≈ 1.1127 × 10⁻¹² F. A sphere of 1 cm radius in vacuum has capacitance exactly 1 statF in Gaussian units; Gaussian-system electrostatics texts and plasma-physics codes express capacitances in statfarads. 1 statF = 10⁵/c² F ≈ 1.113 pF.
About Femtofarads
The femtofarad (fF) equals 10⁻¹⁵ F, the standard unit for transistor gate capacitances in CMOS technology and MEMS sensors. Transistors in 7 nm process nodes have gate capacitances of 0.5-5 fF; MEMS capacitive pressure sensors use sense-gap capacitances of 1-100 fF; integrated-circuit bond-pad parasitics and via coupling are quantified in femtofarads. 1 fF = 10⁻³ pF = 10⁻¹⁵ F.
